Getting Started with Direct3D - Direct3D Rendering - page 36

2. Within the Direct3D Initialization region, change the

CreateWithSwapChain call to pass in the debug flag:
Device.CreateWithSwapChain(
SharpDX.Direct3D.DriverType.Hardware,
// Enable Device debug layer
DeviceCreationFlags.Debug,
new SwapChainDescription()
{

3. Next, we will replace the existing swapChain.Present with the following:

// Output the current active Direct3D objects
System.Diagnostics.Debug.Write(
SharpDX.Diagnostics.ObjectTracker.ReportActiveObjects());

// This is a deliberate invalid call to Present
swapChain.Present(0, PresentFlags.RestrictToOutput);

4. Debug the project ( F5 ) and there should be an exception thrown. The debug

output should contain something like this for the ReportActiveObjects call:
[0]: Active COM Object: [0x11BFB00] Class: [SharpDX.DXGI.
